PIPE-COUPLING.

To all whom it may concern:

Be it known that we, CHRISTIAN F. DoTTs, BAENEY GALLAGHER, and WILLIAM RUMMEL, citizens of the United States of America, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Pipe-Couplings, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to pi e couplings, and more particularly to coup ings for lead pipes, the object being to provide a coupling especially adapted to connect aplurality of pipes when the latter are to be concealed within the framing of a building.

The invention consists of a block or casing formed with one or more water passages, and with projecting tapered nipples, alining with said passages. l v

rI he invention also consists of the combination with a block or casing formed with intersecting water passages, and projecting tapered nipples, of means for detachablysecuring lead pipes upon said nipples,

The construction of our improved coupling will be fully described hereinafter in connection with the accompanying drawing, which forms a part of this specification, and its novel features will be set forth in the appended claims.

In the drawing, Figure 1 is a side elevation of a pipe coupling, constructed in accordance with the invention, and mounted in position within the wall of a building, Fig. 2 is a-ver tical sectional view of the same, Fig. 3 is an elevation of the same, and Fig. 4 is a view in perspective illustrating a modification of the device.

Referring to Figs. 1, 2 and 3, the numeral 1 designates a block preferably square in form, and having projecting from each of two or more of its sides a tapering nipple 2, said nipples alining with and constituting continuations of water passages 3 and 4 formed within the block l. While the construction of the block may be varied to adapt it for use as a one-way, twoeway or three-way coupling, I have shown it in Figs. 1, 2 and 8 as having projecting nipples on only four of its sides, thus providing av three-way coupling. As shown in Fig. 1', the forward nipple 2 projects through a tapered opening formed in a wall 5 of a building or other structure while to each of the other three nipples 2 is se- Speccaton of Letters Patent.

cured the end of a lead pipe 6, said pipe being flared to simply fit over the ni ples, and being secured thereon detachabl) by conical sleeves 7 formed with opposite y projecting ears 8 having bolt-holes 9 registering with perforated lugs l() rojecting in o posite di reotions from the adj acent edges o the block. By means of lbolts l1 and nuts 12, the conical sleeves 7 are firmly secured to clamp the ared ends of the pipes between the nipples and sleeves to form water tight joints. As shown, the sleeves 7 have their interiors formed with two portions. extending in planes which are angular with respect to each other, the outer portion conformin to the shape and diameter of the outer su ace of the main portion of the pipe, while the inner portion conforms to the shape of the outer surface of the ni ple to provide an op osing surface therefor lying in planes su stantially parallel therewith but spaced therefrom a distance sufficient to correspond with the thickness of lthe pipe. There is therefore formed a distinct ang e at the point of meeting of the two portions. When it is desired to form the joint, the sleeve may be slipped over the end of the pipe to a proper point, after which the end of the pipe may be reamed to a sha e to fit the inner portion of the interior of tlie sleeve, the distinct angle at the point of juncture of the two portions protecting the pipe during this operation and roviding a similar angle in the pipe itself, so that when the pipe is placed on the nip le, it will be of a proper shape and size to outer surface of the nipple including its end so as to prevent the leakage of the liquid therebetween, in addition to which the provision of the outer portion of the sleeve, which extends beyond the point where the angle is formed, prevents the formation of any external projection on the pipe at a point which would prevent the free movement of the sleeve over the pipe in a direction away from its end. When the flaring or reaming of the pipe has been completed, the nipple is free to be moved along the pipe, if necessary or desired, to permit the ipe to be placed over the nipple and the s eeve then moved into position, or the pipe and sleeve may be moved into position on the nipple together.

The outer ni ple 2 exten s through the wall opening an is internally screw threaded as shown in Fig. 2 to receive the externally threaded end of a faucet 13. It will be apt the parent that the construction shown, affords a simple and convenient means for connecting water ipes to supply different floors in a house or building, the water supply being through the vertical passage 4 of the block. Instead of threading the front nipple 2 to receive a faucet, said nipple may be similar in construction to the others to effect a pipe connection.

As illustrated in Fig. 4, the block may be provided with a nipple 2 on each of its siX sides, and in this modification a third water passage is provided in the block connecting the two additional nip les, and additional perforated lugs 10 are a so provided.

The utility of the improvement will be fully understood from the foregoing description, and it is obvious that in addition to providing coupling means which render wipe joints unnecessary, we provide a device which serves the double pur ose of a readily manipulated connection forllead pipes, and a faucet securing means.

We reserve the right to make all such variations in the construction as may be included within the spirit of the invention, as defined in the following claims.

What we claim and desire to secure by Letters Patent, is

In a pipe connection, a block having a plurality of water passages, nipples formed integral with the block and constituting a continuation of said passages at each end, sleeves mounted upon the nipples and each having a portion of its length corresponding to the shape of the unclamped portion of the pipe and a portion corresponding to the shape of the outer` surface of a nipple, the relative sizes of the opposing surfaces of the nipple and sleeve being such as to provide an annular space therebetween, a series of pairs of apertured lugs projecting from the sides of the block and with pairs of lugs angularly disposed with respect to each other, apertured ears carried by said sleeves and ositioned in parallelism with respect to the ugs, and holdfast devices extending through the ears and the lugs for maintaining the sleevesv in position.

In testimony whereof we affix our signatures in the presence of two witnessess.
